Crank it up to 10 and let this amp sing. Modeled after the well-known Marshall Super Lead 100 and the Marshall Super Bass 100, this amp offers as much gain as it does tone. Bridge the channels like you would an original and get the clarity and gain of the first channel, and beef it up with the warmth of the second channel. This kit includes 4 JJ EL34 tubes and 3 12AX7 preamp tubes that bring this Class A/B amp into a realm of its own. The amp kit includes the parts to build either the Lead circuit or Bass circuit.

Our beginner level kits such as the tweed champ and tweed deluxe include a manual. If you purchase a kit from Mojotone and do not receive these documents, you can obtain copies by emailing email@example.com or calling 800-927-6656. The Mojotone staff is available Monday through Friday from 8:30 a.m. to 5:00 p.m. EST unless otherwise closed.

Building a fully functional amplifier kit is not an easy task. Before building a kit, one should have the ability to properly solder as well as read and understand a schematic and wiring diagram. While we do our very best to ensure all documentation is current, the included documentation is meant to serve as an overall guide to building the amplifier. Simply following the schematic and wiring diagram does not guarantee you will have a fully functional amplifier. In fact, post build troubleshooting is a common issue across all builds.
Our staff is available to assist with basic troubleshooting needs. There are plenty of online videos available that are helpful with most post build issues. Technical staff is available via email by sending a message to firstname.lastname@example.org. You may also call our sales team to discuss build problems, dial 800-927-6656 and press 1 for sales.
Building a tube amplifier takes time, dedication, resources and most importantly... Skills! The experience of building an amp can come with some frustration, the reward of completing the build is definitely well worth your time. Please review the wiring diagram, schematic and manual (if applicable) prior to making your purchase. Mojotone will not accept any returns on amplifier kits and/or parts that have been assembled, soldered or modified.
Ratings & Reviews
It sounds right
by Bill -
Built amp for son's graduation. Couple full Saturdays to build. Mojotone promptly shipped 2 missing parts. One bad solder joint took few hours to find. Son wanted to cry after first song he played "The New" by Interpol. Says he had been playing it for months and this was first time it sounded right. Will rock his college band. Versatile sounds great bass or lead guitar.
